DRAINAGE APPARATUS.

SPECIFICATION forming art of Letters Patent No. 260,793, dated July 11, 1882.

' Application filed September 16, 1881. (No modeLl To all whom it may concern:

Be it known that I, CHARLES SHINKLE, a

ed new and useful Improvements in Drainage Apparatus, of which the followingis aspecification. F

Myinvention relates to devices employed for draining swamps, low-lying lands, sewerage, &c., into the sea or into natural outlets against a head of water standing ordinarily at a higher level; and it consists in the construction and arran gement of apparatus hereinafter described.

In the accompanying drawings, illustrating my invention, Figure l is a sectional view of a dam separating the waters to be drained from the outlet-basin,showin g myimprovement applied thereto. Fig. 2 is a sectional view of a modified form of the drainage pump, and Fig. 3 a sectional view of adam to which a further modified construction of theapparatus is applied.

In the drawings, A designates a dam separating a catch-basin, B, into which the drainage is collected from the outer basin, 0, which may be a river, lake, or oulet of any kind.

In the dam A, I place one or a series of cylinders, D, arranged horizontally at the lowest level to which it is desired to drain the basin B, and arrange therein one or more propellerwheels, E, upon a central shaft, F, mounted in suitable bearings in the standards f, as a means of drawing and forcing the water from.

the basin B into the outlet 0. Although I have shown two wheels in the cylinder 1), yet ordinarily, when the head of water outside is not excessive, a single wheel E will be suflicient. 7 Where a single wheel is employed it is preferably placed near the out let end of thecylinder, as shown, and the cylinder-itself isin such case preferably constructed in a slightly conical form, having a larger 5 diameter at the receiving end than at the discharging end, in order to insure a ready flow of water to supply the suction of the pump.

The cylinder D is enlarged slightly at the end where the wheel is placed, so that a wheel equal to or greater than the diameter of the cylinder may rotate therein in order to prevent the backlash of water and secure a steady flow outward. As contributing somewhat to a perfeet action in this regard, the blades of the propeller-wheel may terminate outwardly in a band or cylindrical flange turned and fitted to the enlargement referred to. The pitch and number of the blades must be determined by the power employed and the head of water resisting the outflow, as will be readily understood by those conversant with the subject.

In Fig. l I have shown the shaft F extended into a well, G, where the motive power is applied either bycouplingthe driving-engines directly to a crank, g, or by beltingito a pulley,

g. This arran gementis desirable where wheels of considerable size are used for moving large quantities of water against considerable resistance, in which case a high speed is required; but ordinarily the power may betransmitted from above by a vertical shaft and bevel-gear- The outer end of the eylinder'D is provided with ahinged flap-valve, H, opening outward. This will ordinarily operate automatically to prevent baekflow by the greater pressure without but a lifting rope or chain, h, may be attached and operated from above.

Where the head of water on the outside is variable, as in the case of tides, or water affected by winds, it may occur that the headof water in the catch-basin will exceed that with-.

out, in which case the driving-engines maybe stopped, and the water allowed to flow outward by its natural gravity.

In Fig. 2 the cylinder is formed with an elbow, by which its receiving-mouth opens vertically, allowing the wheel to be mounted on a vertical shaft for convenience of operating.

In the modification shown in Fig. 3 the cylinder is placed wholly in the catch-basin B and its exit end carried upward and over the dam. This construction may be necessary where it is not desirable to perforate the dam to place the apparatus in position; but otherwise the first-mentioned construction is preferred.

It will be readily understood that in the drainage of swamps and sewerage catch-basins a large amount of dirt, earth, gravel,weeds, 850., is liable to be drawn through the apparatus, and that the latter, to be efficient, must therefore be of the simplest construction and aeces sible to repairs; the arrangement of apparatus shown I have found to be the best under all circumstances of use.

I do not wish tobe understood as claiming broadly a submerged pipe or cylinder provided with apropeller-wheel for creating an artificial current and drawing off stagnant waters, for such, independently considered, is old.

Having described myinvention, I claim and desire to secure by Letters Patent 1. The apparatus for draining swamps and the like into tide-water or other outlet,consisting in a dam separating the drainage catchbasin from the outlet waters, and one or more channels extending at or below the desired drainage level through said dam, and provided with valves acting automatically to prevent backflow, and a propeller-wheel operating in the cylinder upon a central shaft, substantially as specified.

2. In combination with the dam A, separating a catch-basin, B, from the outlet 0, a cylinder, D, extending horizontally through the dam, and provided with one or more propeller- 20 wheels, E, arranged upon a central axial shaft, find an outer valve, H, substantially as speci- In testimony whereof I have hereunto setmy hand in the presence of two subscribing witnesscs.
